Variations in surface air temperatures. Part 3: the Antarctic, 1957-82.

Abstract

Antarctic temperature variations for 1957-82 have been objectively analyzed by gridding monthly data, from 16 stations, onto a 5o latitude by 10o longitude grid, from 65 to 90oS. These gridded data were used to calculate monthly values of the spatial mean temperature south of 65oS. Relationships between Antarctic temperatures and various parameters are investigated using linear trend and correlation analyses. The most significant correlations between mean Antarctic temperature and sea ice extent averaged around Antarctica are found in spring: warm springs tend to be associated with anomalously large maximum sea ice extent. -from Authors
